“Pure Satisfaction”
All Aquasana products oer a 90-day 100% money back guarantee. (A 1 year warranty is included, which

Important:
For the first 72 hours the faucet diverter valve will drip intermittently, until the filters become fully
saturated. Once they are saturated you should anticipate a residual flow of water each time you use the
filter, as the system is vented and designed to clear the line.
Precautions:
Aquasana is not liable for consequential or incidental damages due to improper installation.
• Never use this system on constant pressure applications such as ice makers or drinking fountains.
• Filter is only to be used with cold water.
• If the faucet diverter valve does not t, you will need to install one of the brass faucet adapters before
attaching it. The brass faucet adapters can be tightened using the install tool. (if the supplied brass
faucet adapters do not fit you can obtain the right size from your local hardware store. Be sure to
bring your aerator and diverter valve to find the perfect match.)
• Make sure the rubber washer is in place inside the chrome swivel collar on the diverter valve.
• If you experience a leak at the hose connection, disconnect and re-seat the hose.
• If you will not be using your lter for greater than 10 days, remove the lters, place them in a plastic bag
and freeze them to avoid growth of mold or mildew.
* Supplied brass faucet adapters and seals are not included in or covered by the system certification.
